To all whom it maty` concern:

Be it known that I, SAMUEL S. EVELAND, a

r citizen of the United States, residing at the lze citly of Philadelphia, in the county of Philade phia and State of Pennsylvania, have invented certain new and useful Im rovements in Ball-Bearings, of which the fo lowing is a specification;

'Objects of the present invention are to provide an efficienti and compact bearing in which the concentric bearing members are movably held in proper relation by the balls between them and in which there 1s a spacer for the balls, to provide for convenience in assembling the parts, and to so construct and arrange the parts that they remain in assembled relation and can be handled in a body.

The nature, characteristic features, and

scope of my invention will be more fully understood from the following description, taken in connection with the accompanyingldrawin s, forming part hereof, and m whic lgure 1 is an elevational view of a bearin embodying features of the invention, an

Fig. 21s a sectional view. is an edge view of the ball spacer and retainer with some of the balls removed and Figs. 4 and 5 are face and edge views, partly m section, showing the ball retainer or spacer with part of the balls removed.

In the drawings, 1 and 2 are concentricallyarranged rings, of which the ring 2 is grooved upon lots inner face and the ring 1 is grooved upon its outer face, so a's to constitute grooves in which the balls 3 run. .n

4 and 5 are notches in the rings 2 and 1, and they are an example of means by which the balls may be placed between the rings and in the grooves thereof.

The ballretainer consists, of a crowntoothed ring 6, havin the ends 7 of its teeth enlarged and provide with concave radiallyarranged faces 8 to permitl of the insertion and removal of the balls and having the shanks of the teeth cut away and inclined, as at 9, so as to form, With countersinks 10 in the rm proper, ball-sockets into and out of p which t e balls may be sprung.

Balls are inserted between the rings 1 and held .apart by' the retainer. At t 2 and are then arranged with spaces between them. The retainer's then inserted between the rings such a way that the balls enter through the spaces bounded by the concave portions 8, springing their way into the pockets formed by the countersinks 10, the under:

sides of the enlarged ends, andthe inclined portions'9.

Thus the various parts of the device are detachably connected together in a bed; against accidental displacement, While the als are free to run in the grooves and are lproperly e same time t e various members may be readily taken apart for repairs or other purposes.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A bearing com risino' the combination of concentric rings w ereolr` one is grooved on its inner and whereof the other is-grooved on its outer face, balls interposed between said 'rings and arranged in said grooves, and acage comprising a crown-toothed rin having beends of its teeth enlarged and provided with concave faces to permit of the insertion of balls and havin the shanks of the teeth inclined to form with said countersinks and the enlarged heads ball-sockets, substantially as described.

2. A bearing comprising the combination of concentric rlngs whereof one is grooved on its inner and whereof the other is grooved on its outer face, balls interposed between said rings and arranged in said grooves, and a cage comprising a crown-toothed ring having between its teeth ball-seats and having the ends of its teeth enlarged and provided with passages to permit of the insertion of balls and having the shanks of the teeth arran ed to form with said ball-seats and the e arged heads ball-sockets, substantially as described.

In testimony whereof I have hereunto signed my name.
